1.2. Concept of information

The word "information" in Latin means information, clarification, presentation.

Information refers to information about objects and phenomena of the surrounding world, their properties, characteristics and condition, perceived by information systems. Information is not a characteristic of the message, but of the relationship between the message and its analyzer. If there is no consumer, even a potential one, there is no sense in talking about information.

In computer science, information means some sequence of symbolic symbols (letters, numbers, images and sounds, etc.) that carry a meaning and are presented in a manner understandable to a computer. Such a new character in such a sequence of characters increases the information volume of the message.
